Casey Anthony Is Dreading Court Appearance: Source

Casey Anthony got some unwelcome news this week when her attorneys accepted a subpoena that will force her to take the stand in the civil case against her.

PEOPLE has learned that Anthony, 26, is angry that her required appearance will affect her plans to leave the country after her probation ends in August. She will now have to be available to testify.

"Casey was really hoping to leave Florida and never look back," explains a source close to her. "She was really ready to move on with her life. This has ruined everything."

Anthony will have to answer tough questions about her statements in the days after her daughter, Caylee, was reported missing – and later turned up dead. She claimed that a babysitter named Zenaida Gonzalez had kidnapped the girl, an allegation that turned out to be untrue. Now a woman by the same name is suing Anthony for defamation.

"Casey just wants this case to go away," says the source. "She definitely doesn't want to testify, and she's annoyed that she has to."

These days, Anthony is living in South Florida. She ventures out infrequently, afraid that she will be recognized. But according to two sources close to her, she looks much different. "Quite honestly, she's gained a few pounds," says the source. "She does nothing but sit in front of her computer and eat." Anthony remains unemployed and broke, and, according to probation reports, she recently stopped attending counseling.

One thing she does do: speak regularly with her estranged mother, Cindy. Sources close to the Anthony family have confirmed that Casey began mending her relationship with Cindy several months ago. She does not communicate with her father, George, whom she accused of molesting her.

Anthony will return to the Orange County courthouse to testify in January 2013.
